Subspecies
editThe species Tetrathemis irregularis includes the following subspecies:[5]
- Tetrathemis irregularis irregularis Brauer, 1868 - found in South-east Asia and New Guinea
- Tetrathemis irregularis cladophila Tillyard, 1908 - found in Australia and the Aru islands
Etymology
editThe genus name Tetrathemis is derived from the Greek τετρα- (tetra, "four") and -themis, from Greek Θέμις (Themis), the goddess of divine law, order and justice. In early odonate taxonomy, names ending in -themis were widely used for dragonflies. The name refers to the apparently four-sided triangle in the wings.[2][8]
The species name irregularis is derived from the Latin in- ("not") and regularis ("regular" or "orderly"). The name also refers to the irregular four-sided triangle in the wings.[2][8]
